First, you need the root certificate (.pem file) of your company's web filtering/security proxy.
- Open the Keychain Access app (search via Spotlight
Cmd + Space). - In the search bar at the top right, type the name of your security solution (e.g.,
Zscaler,Netskope,Cisco). - Look for the Root Certificate (Root CA) in the list (it usually has a blue certificate icon).
- Right-click the certificate and select "Export [Certificate Name]..."
- Choose your Desktop as the save location, select
.pem(Privacy Enhanced Mail) as the file format, and save it.

proxy_cert.pem.
